How can I get attributes like “numpt” from input 2 in a wrangle?

If you want to get an attribute (lets say color) from a specific point number (lets say 123456) from input 2, you can use 
@Cd = point(1, 'Cd', 123456);
If you have the same number of points on both inputs and you want to get an attribute from the corresponding point on input 2 you can use this shortcut 
@Cd = v@opinput1_Cd;
Where the number 1 describes the input port.

“i@opinput1_numpt” is not working for me.

Ah, you want the number of points on input 1?
@number_of_points_on_input_1 = npoints(1)

i@group_test= i@group_grass + point(1,"group_grass",@ptnum) ;

doesnt seem to work for me to add the group from the second input.

i@group_test = i@opinput1_group_grass;

alternatively also this, especially if you don't necessarily test for current point on second input:
i@group_test= i@group_grass || inpointgroup(1, "grass", @ptnum);
